Hard x-ray free electron lasers (XFELs) are great diagnostic tools in modern science. A number of XFELs have been constructed worldwide in the past decade [1]}, [2]}, [3]}, [4]}, [5]}. In the past, Los Alamos National Laboratory has expressed interest in hosting a similar facility to support ongoing Programs [6]}. The facility has been envisioned based on a conventional radio frequency (RF) accelerator technology. As a result, the estimated size and cost of the anticipated facility turned out to be large, which significantly decreased attractiveness of this project.
